Purpose:
To collect real data to input into a computer spreadsheet
Objective:
To collect data on running speeds of various individuals in your
class to determine the average running speed for a distance of 20
meters.
Materials:
- meter stick
- stop watch precise to the nearest 0.001 second
- 20 meter in length flat area
Procedure:
- Using a meter stick, mark off a linear distance of 5 meters,
10 meters, and 15 meters on a flat surface, such as a playground,
parking lot or track.
- Have each student predict how long it will take to run each of
these distances. Have each student give reasons for their
predictions, explaining the difference between a hypothesis and a
guess.
- Have one student be the time-keeper at the finish line and
another student record each individual's time.
- Each student should run the distance at least 3 times for
accurate results.
- Fill in Chart A.
- Choosing the fastest speed for each distance, convert to miles
per hour.
- Record the times, speeds, and names of all the other
classmates and enter into a spreadsheet.
- Use the information in chart B to label the data headings.
- Use formulas within the spreadsheet to calculate average times
(rounded to the nearest 0.01 second) and average speed ( in both
meters/second and miles per hour)
- In the last line of the spreadsheet , include calculations to
average the entire class data.
